I have a very similar issue: on boot there is a first request for the LUKS passphrase, but that fails three times. Then a bit later it asks again, but now it works
Without splash screen I get the following order - USB drive with encrypted root partition detected - requests passphrase to open encrypted partition, but fails (3 times) - runs /scripts/local-premount - requests passphrase to open encrypted partition, now succeeds Kernel: # uname -rv 7.0.0-38-generic #38-Ubuntu SMP PREEMPT_DYNAMIC Fri Sep 4 09:10:14 UTC 2026 # Attached is the boot screen to the moment where entering the correct passphrase would work. ** Attachment added: "IMG_20261008_155606.jpg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161181/+attachment/6007245/+files/IMG_20261008_155606.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2161181 Title: [Regression] LUKS root passphrase rejected on kernel 7.0.0-28, works on 7.0.0-27 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161181/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
